7/1/2001 - Conference papersTo study bump mechanisms, conditions in the vicinity of a deep longwall mining face in bump-prone strata were monitored using three discrete systems in an effort to increase understanding of mining-induced stress redistribution and bump potential.

6/1/1999 - Conference papersVarious methods of monitoring slip movements on bedding planes, as well as examination of rock burst damage in stopes, suggests that rock bursts in the Lucky Friday Miner are closely associated with these movements.

8/1/1998 - Conference papersA comprehensive survey of mine seismicity a rock bursting during development of two sublevels at the Lucky Friday Mine, Mullan, ID, was conducted to better define rock failure mechanisms and sources of ground control hazards.
-
11/1/1997 - Technology NewsThe use of seismic tomography to identify geologic hazards in underground mines is discussed.
-
1/1/1997 - Peer reviewed journal articlesIn an effort aimed at monitoring mining-induced stress changes that may influence ground failure, the U.S. Bureau of Mines conducted a series of active 3-D seismic tomographic surveys at the Homestake (Lead, South Dakota) and Lucky Friday (Mullen, Idaho...

1/1/1997 - Conference papersRock masses in deep-level mines are subject to high stresses, which can result in unexpected failure of rock into mined-out openings. Personnel from two research centers of the former U.S. Bureau of Mines, Spokane and Twin Cities, investigated a rock b...

1/1/1976 - Reports of InvestigationsA seismic system which utilizes in-mine geophones to detect trapped miners has been developed. Tests at the Bureau of Mines safety research mine at Bruceton, Pennsylvania, and at two operating mines indicate such a system has a maximum detection range i...
